Can I assume that all the shoreline elevation issues will be dealt with by the shoreline classification fix? If so then I will not post terrain defects that show right on the shoreline. Will this fix correct elevation issues?

This happens when the data for oceans do not match too well the more detailed terrain data, creating underwater cliffs. I'll be adding some filtering there to alleviate the problem, because even the shoreline treatment would not fix it.

This also causes "toothy" shores problem that can be seen elsewhere.

And you mean these underwater cliffs? (see attachment) When you change the water colour you find that the underwater cliffs become more apparent and they magnify if zoomed in or out.
